我在使用Nick Gammon's Regexp library时出现此错误。下面的错误是：在Arduino IDE中使用正则表达式库时对'longjmp'的未定义引用
libraries/Regexp/Regexp.cpp.o:(.text._ZL5errorc+0x4): undefined reference to `longjmp' libraries/Regexp/Regexp.cpp.o: In function `error': /Users/jaiprak/projects/Arduino/libraries/Regexp/Regexp.cpp:640: undefined reference to `longjmp' libraries/Regexp/Regexp.cpp.o: In function `max_expand': /Users/jaiprak/projects/Arduino/libraries/Regexp/Regexp.cpp:640: undefined reference to `setjmp' libraries/Regexp/Regexp.cpp.o: In function `MatchState::Match(char const*, unsigned int)': /Users/jaiprak/projects/Arduino/libraries/Regexp/Regexp.cpp:640: undefined reference to `setjmp' collect2: error: ld returned 1 exit status exit status 1 Error compiling for board Generic ESP8266 Module.
，这是我的Arduino代码：
#include <Regexp.h>
// called for each match
void match_callback (const char * match, // matching string (not null-terminated)
const unsigned int length, // length of matching string
const MatchState & ms) // MatchState in use (to get captures)
{
char cap [10]; // must be large enough to hold captures
Serial.print ("Matched: ");
Serial.write ((byte *) match, length);
Serial.println();
for (byte i = 0; i < ms.level; i++)
{
Serial.print ("Capture ");
Serial.print (i, DEC);
Serial.print (" = ");
ms.GetCapture (cap, i);
Serial.println (cap);
} // end of for each capture
} // end of match_callback
void setup()
{
Serial.begin (115200);
Serial.println();
unsigned long count;
// what we are searching (the target)
char buf [100] = "The quick brown fox jumps over the lazy wolf";
// match state object
MatchState ms (buf);
// original buffer
Serial.println (buf);
// search for three letters followed by a space (two captures)
count = ms.GlobalMatch ("(%a+)()", match_callback);
// show results
Serial.print ("Found ");
Serial.print (count); // 8 in this case
Serial.println (" matches.");
} // end of setup
void loop() {}
